Abstract

Various factors (e.g., hand preference, object properties) constrain reach-to-grasp in hemispace. With object use, end-state comfort (ESC) has been shown to supersede the preferential use of one hand at the midline. To assess how location, size, and orientation of objects (dowel, mallet, cup) influence preferred-hand use and ESC (N = 50; Mage = 20.83), three preferential reaching tasks were implemented. Object location influenced hand selection in all tasks, along with size (cups) and orientation (mallets). Object location and orientation influenced ESC, but only with dowels and mallets. When oriented away from the preferred hand in hemispace, there was a higher occurrence of non-preferred hand use to facilitate ESC. Overall, findings add to understanding of ESC and preferential reaching with varying task demands.

优先到达和最终状态舒适度:任务需求如何影响运动计划

摘要

各种因素(例如,手的偏爱,对象属性)限制了半空间中的可抓握范围。在使用对象时,已证明最终状态舒适度(ESC)可以代替在中线时优先使用一只手。评估物体(销钉,槌,杯)的位置,大小和方向如何影响惯用手和ESC(N = 50; M年龄= 20.83),实施了三个优先到达任务。对象的位置会影响所有任务中的手选择,以及大小(杯)和方向(小号)。物体的位置和方向会影响ESC,但仅会影响销钉和槌。在偏向于偏向于半空间的首选手的情况下,非首选手用于促进ESC的可能性更高。总体而言,发现增加了对ESC的理解,并随着任务需求的不同而优先达成。
